Experience:Unknown dosage - Ego death and becoming one with a singular entity

I had this experience on 3 blotters of what I believe to be 25I-NBOMe due to the taste and numbness in my mouth when I took it although I am not sure of the exact dosage.

At what I think was the peak of my trip everything in the room (including me) melted into itself and became one single thing, I experienced ego death and everything collected into to separate spheres of positive and negative which then came together and became neutral or nothing and everything at the same time. I don't have much memory of the trip but I know when I had come partially back to reality I remembered all the people in the room as a part of 1 singular entity that I was also a part of, and I also saw a few people who weren't actually there.
